Abstract

The migration of telephone services by a telecommunications carrier from a PSTN to an IP network entails that problem that when it is not possible for some telephone subscribers to migrate to the IP network due to the types of their telephone lines or services they subscribe to, other subscribers also cannot migrate to the IP network until the former subscribers migrate to the IP network. The present invention provides a media gateway that enables a gradual transition from a PSTN to an IP network on a subscriber-by-subscriber basis or on a service-by-service basis so that a telecommunications carrier can efficiently migrate its subscribers while continuing to provide the services the subscribers currently use and reducing burdens on the subscribers.
